Studio Technologies Model 391 Dante Alerting Unit

Model 391 Dante Alerting Unit

The Model 391 Dante Alerting Unit builds on the limited capabilities of the "beacon" or "strobe" devices that are ubiquitous with analog party-line (PL) intercom systems and adds a broad range of new and enhanced features. The Model 391 will respond to 20 kHz "call" signals that are commonly utilized in both legacy analog and modern digital party-line intercom circuits. Upon detecting a call signal the Model 391 can provide a visual indicator, enable an audio sounder output, and even activate an analog line output. Each of the Model 391's alerting resources can be individually optimized to meet the unique requirements of many applications. The STcontroller personal computer application is used to select from a wide range of operating choices. The compact, portable unit is compatible with Dante audio-over-Ethernet installations and requires only an Ethernet connection with Power-over-Ethernet (PoE) capabilities for operation. Typically applications will find the Model 391 applicable for use in theater, sports, and broadcast facilities.

The Model 391 is directly compatible with the call signals generated by the popular Studio Technologies Model 370 and Model 371 Intercom Beltpacks. These Dante-connected user devices generate 20 kHz tones whenever their call button is pressed. Model 391 applications can also employ the Studio Technologies Model 45DC or Model 45DR Intercom Interface units to provide compatibility with legacy analog PL intercom systems. The Model 45DC is compatible with Clear-Com PL circuits that use a DC voltage to indicate call activity. The Model 45DR supports the TW-series PL intercom circuits from RTS which directly use 20 kHz tones for call activity. Both interfaces will convert the associated analog PL circuit's audio and call signals to Dante digital audio. Once in the Dante "world" the call signals and user audio is compatible with the Model 391 Dante Alerting Unit as well as user beltpacks such as the Model 370 and Model 371.
